[TYPO3] T3_onloadWrapper problem

[Sergio Catalá]

Hi, 

got a problem with the extension "de_addbodyjscript". It works fine for
one of my servers (loads Javascript code) but not for the other one. 

I noticed that my browser throws the "T3_onloadWrapper() is not defined"
error.

If I understood the extension, it should add an additional 'onLoad'
event to the page's body, but doesn't even do that. 

Could anyone give me any clue?
